Preview deleted all my notes

Hi,

So I have an issue where preview on my MacBook was keeping my comments/notes but then several things happened:

1) The clickable note disappeared after a few weeks and all I could do to see the note was to open the sidebar under "notes and highlights" but even then I couldn't view the note, only the first 2 lines

2) Under notes and highlights all my notes disappeared two days ago

3) I tried starting in safe mode but the issues persisted and while I could restore a backup it seems from the forums that this issue is here to stay

I was taking notes for several large paper's and this has set me back so far. I viewed other posts and none had any solutions and simply resigned themselves to the fact Apple refused to do something about this software bug that has been present and growing worse in the last few iterations

I am now using a free version of Adobe Acrobat user DC which has all the features of Preview I used and more.

Does anyone have a solution to restore the lost notes in preview?
